How to locate the vacuum leak?

You will have to find it.While driving your vehicle has minimal vacuum it creates the most when idling or at a stop. You are having to give it gas to compensate for the car getting to much air. Check all the hoses that attach to the intake and check the intake use carb cleaner it works perfect.

You could be looking for a small hole or a large one. Next to your air filter is a MAF mass air flow meter. It tells the computer how much air is coming into the engine between the MAF and the O2 sensors in the exhaust there is a problem. Your computer is telling you that there is more air getting in somewhere more than what the MAF send signal to it. So this means if a vacuum leak is your problem which it most likely is.Its are sucking/getting more air either around the intake gaskets or around the vacuum lines going to the intake or around the throttle body or the sensors attached to it. Most of all the hoses on your engine are smaller than your thumb are vacuum lines. You need to spray carb cleaner all over the engine and around these hoses to find a leak. The rpms will increase when you hit a leak because the car will suck the carb cleaner in and use it as a fuel and it will rev slightly. There is no common area of failure and there is not a common part that fails. You will have to take it to a dealer to repair or find the problem yourself. I highly recommend you give it a shot before sending it to a technician.

This details will help.

Thanks.
